Double up sngs are nice for building stacks or just making a few bucks from.

Start off easy, and try avoid going all in even with high pairs as this is the phase off the game where you can get called with anything. I doesnt know how many times ive lost with a high pair in the first few hands, against a donk calling with absolute trash.

Let a few players get knocked out, while trying to avoid to big losses to your stack.

Dont play to many drawing hands, and if you do you should try avoid going all in unless nuts, or having a damn lot of outs.

dont pick fights with bigstacks,unless absolutely necessary and if you do expect to be pushed around.

When you are i position (sb or button) you can try to do some steals from the smallstacks.
